Biography
Pedro Calungsod was born in Iloilo, Visayas, Philippines on 21 July 1654, and he was educated at a Jesuit boarding school before mastering the Roman Catholic Church's catechism and becoming fluent in Spanish. In 1668, at the age of 14, he was chosen to accompany Roman Catholic missionaries to the island of Guam to help proselytize the locals. Many of the local Chamorros were baptized and became Catholics, but a Chinese criminal exiled to Guam from Manila named Choco claimed that the baptismal water used by the missionaries was poisonous. After several baptized infants died of sickness, the island's medicine men and young men grew angry with the missionaries, holding them responsible for the infants' deaths. On 2 April 1672, Calungsod and the priest Diego Luis de San Vitores were ambushed by the villager Hirao, who had been sent to murder them after they baptized the daughter of the local pagan chieftain, Mata'pang, who opposed their mission. Calungsod was known to have martial prowess, but he was unarmed as per San Vitores' orders; instead of escaping and saving himself, he chose to stay behind and help San Vitores in an escape attempt. However, Calungsod was struck in the chest by a spear and was then beheaded, and San Vitores quickly absolved Calungsod before also being killed. Calungsod was canonized on 21 October 2012 by Pope Benedict XVI, and he is regarded as the Protomartyr of Guam.
